I love Club Pilates. They are the bomb. They offer classes almost every hour most daya. The facility is well equipped, perfectly maintained and the staff is terrific. I have been taking classes for almost a month there now and each instructor I've had is great. There is a ton of variation in the classes even when they are listed as the same type of class so you never get bored. It's easy to follow along and they instruct you to correct anything you are doing incorrectly.
I haven't had any trouble booking classes and even when they're full, you can go on a waitlist and I almost always get in since people cancel. They made it really simple for me as a part timer here with a month of unlimited classes while I was here for the month and a pack of classes to use over the next year when I come in from time to time. I love that you can book ahead online. It's so simple to do!
